Hubble Finds that a Bizarre X-Shaped Intruder Is Linked to an Unseen Asteroid Collision

October 13, 2010: Last January astronomers thought they had witnessed a
fresh collision between two asteroids when images from
NASA's Hubble Space Telescope revealed a bizarre X-shaped object. After using Hubble to track the oddball
body for five months, astronomers were surprised to
find that they had missed the suspected smashup by a
year. The science results are reported in the October
14 issue of the science journal Nature.
